MWD BF Instruction manual
Functional description
The MWD BF is a radar motion detector with direction identification, which has been especially
designed for applications in the area of industrial gate- and barrier systems. In some cases, the
operational parameters may also be adjusted with an infrared remote control.
Motion detection is done according to the Doppler’s principle. The sensor sends out 24 GHz
microwaves. These microwaves are reflected by objects in motion and thus their frequency
changes. The sensor receives these altered frequencies and analyses them. Thus, each motion
within the detection range is recorded, analysed by a logic and transmitted to the gate- resp.
barrier control by connecting potential-free change-over contacts.
Range of application:
Entry-/access recognition for the drive of industrial gate- and barrier systems
Special features:
• Insensitive to fluctuations of temperature and humidity
• Distinction vehicles/persons
• Reversible and cutoff direction logic
• Adjustable sensitivity
• Potential-free relay exit with change-over contacts
• Large supply voltage range - AC or DC
• Adjustment of operational parameters by key buttons or infrared remote control
• Compact plastic housing
• IP 65 housing
• Easy and fast installation with mounting bracket

2 Installation
2.1 Place of installation
The device is centrally mounted above the area to be monitored. Both wall- and ceiling mountig
are possible. The maximum mounting height is approx. 6m.
Hints for planning and installation:
• The device has to be mounted vibrationless.
• In order to avoid incorrect release, there must not be any objects in motion within the
radiation field.
• There must not be any fluorescent tubes within the radiation field of the detector.
• It should be avoided that the radiation fields of two motion detectors overlap, since this may
lead to incorrect releases.
• Do not install behind objects, building coverings or elements.
• If the motion detector is exposed to rain or snow, it should be adjusted to directional
recognition.
• If conductive floors are used and the radiation direction is almost vertical, incorrect releases
may be caused by reflections.
2.2 Mounting of the bracket
The bracket is suitable for both wall- and ceiling mounting. In case of ceiling mounting, it has to
be turned by 180° opposite the housing of the motion detector.
2.3 How to connect the motion detector
Connection is done as shown in figure 2. Deposit the leads of the flexible connecting cable
10 cm from the appliance, lead it through the lateral PG-screwing and fix it.
In case of DC power supply, polarity is insignificant.
10cm
2.4 How to screw down the housing
The cover should be screwed down with a torque of approx. 1 Nm. Put the cover evenly into the
groove of the housing and screw it down.
Attention! If the cover is tilt, for example due to squeezed cable leads in between the screw
guides, the tightness of the housing is not guaranteed!
